    • Systems and methods of managing access to digital content are described. In one aspect, a novel digital content access management system enables users to register previously owned digital content and, subsequently, allows users to access the registered content using any electronic device that is connected to the system. Digital content may be pushed or pulled from any electronic system that is connected to a network—no matter where it is located—to any other electronic system that is connected to a network. A novel business model, as well as a system and a method for implementing this model, also are described. In accordance with this business model, payments are made to content providers upon registration of the previously owned digital content. In this way, the monetary interests of content providers may be protected (even when a user registers borrowed digital content, for example), while enhancing the ability of users to interact with their licensed digital content.
    • 描述了管理数字内容访问的系统和方法。 一方面,一种新颖的数字内容访问管理系统使得用户能够注册先前拥有的数字内容,并且随后允许用户使用连接到系统的任何电子设备访问注册的内容。 数字内容可以从连接到网络的任何电子系统(无论其位于何处)被推送或拉出到连接到网络的任何其他电子系统。 还描述了一种新颖的商业模式,以及用于实现该模型的系统和方法。 根据这种商业模式,在先前拥有的数字内容注册后,向内容提供商付款。 以这种方式,内容提供商的货币利益可以被保护(即使当用户登记借用的数字内容时),同时增强用户与其许可的数字内容交互的能力。

    • The invention features an improved, photo hull based method of generating a three-dimensional representation of a visual scene based upon a set of multi-view reference images. In one aspect, a visual hull containing the visual scene is computed. Visibility of points on the computed visual hull with respect to each reference image is computed. Photo-consistency of points on the computed visual hull along rays back-projected from a desired view is computed based upon reference images having visibility of the points. A photo hull containing the visual scene is generated by stepping along each back-projected ray. The photo-consistent points visible in the desired view are colored using color information contained in reference images having visibility of the photo-consistent points.
    • 本发明的特征在于基于一组多视图参考图像生成视觉场景的三维表示的改进的基于照片的船体的方法。 在一个方面,计算包含视觉场景的视觉外壳。 计算相对于每个参考图像的计算的视觉船体上的点的可见性。 基于具有点的可视性的参考图像来计算沿着期望视点反投影的光线的计算的视觉船体上的点的一致性。 包含视觉场景的照片船体通过沿着每个后投射的光线进行生成。 在所需视图中可见的光一致点是使用包含在具有光一致点的可视性的参考图像中的颜色信息进行着色的。
